This is a limited edition item, possibly from the Inter-High school competition, so the sleeves are made differently from regular Phiten T-shirts. It's lightweight and quick-drying, making it suitable for practice wear in club activities. I've taken photos of any noticeable flaws, but please understand that I may have missed something. I have a Shiba Inu and keep it indoors. I try my best, but there might be some dog hair that I haven't removed. I'm in the process of decluttering, so I'll be listing items gradually. Thank you for your understanding.
